Targum - A Multilingual New Testament Translation Corpus

Targum is a multilingual New Testament translation corpus with unprecedented depth in five European languages: English, French, Italian, Polish, and Spanish. It contains 651 translations (334 unique) collected from 13 source libraries and spanning 1525–2025.

This dataset contains the public release subset: 302 translations distributed under public domain or open licenses. The remaining 349 copyrighted translations are not distributed but are available to researchers upon request.

Named after the ancient Aramaic translations of the Hebrew Bible (תרגום, "translation"), the corpus prioritizes vertical depth over linguistic breadth, making it possible to computationally analyze a wide spectrum of historical periods and confessional traditions within each language.

Also available on GitHub: mrapacz/targum-corpus.

Corpus Scale

Language	Code	Total	Unique	Public subset
English	eng	390	194	191
French	fra	78	41	44
Spanish	spa	102	53	29
Polish	pol	48	29	25
Italian	ita	33	17	13
Total		651	334	302

"Total" is the number of translation instances collected across all 13 source libraries (the same translation may appear on multiple sites). "Unique" is the number of distinct translation editions after deduplication. "Public subset" is the number of instances distributed in this dataset under public domain (237) or open licenses (65).

Structure

  {site}/
    {iso}/
      {id}.jsonl        # one verse per line
works.tsv               # one row per translation work (a work groups all editions of one underlying translation)
editions.tsv            # one row per edition, with copyright + provenance

# Same tables are also available as .json (lists preserved as arrays).

Each JSONL file:

{"book": "MAT", "chapter": 1, "verse": "1", "text": "The book of the generation of Jesus Christ..."}
{"book": "MAT", "chapter": 1, "verse": "2", "text": "Abraham begat Isaac..."}

Embeddings

Pre-computed text embeddings are available for all translations, produced by several encoder models at chapter and/or verse granularity:

Model	Granularity	Files	Size
Qwen/Qwen3-Embedding-0.6B	verse	656	~7.7 GB
Qwen/Qwen3-Embedding-8B	chapter	656	~1007.1 MB
Qwen/Qwen3-Embedding-8B	verse	656	~74.5 GB
nvidia/llama-embed-nemotron-8b	chapter	656	~1007.5 MB
sentence-transformers/LaBSE	chapter	656	~1.1 GB
sentence-transformers/LaBSE	verse	656	~22.8 GB

Embeddings are stored as Hive-partitioned Parquet files:

embeddings/
  {model}/
    language={iso}/
      site={site}/
        translation={id}/
          granularity={chapter|verse}/
            data.parquet

Where {model} uses XxX as a separator (e.g. QwenXxXQwen3-Embedding-0.6B). Each data.parquet contains columns key (e.g. MAT 1 for chapter, MAT 1:1 for verse) and value (the embedding vector).

Loading chapter embeddings for one translation:

import pandas as pd

df = pd.read_parquet(
    "hf://datasets/mrapacz/targum-corpus/embeddings/"
    "QwenXxXQwen3-Embedding-0.6B/language=eng/site=ebible.org/"
    "translation=eng-web/granularity=chapter/data.parquet"
)

Metadata

Each translation has three layers of metadata:

• works.tsv — one row per translation work (work_id, display name, abbreviation, language, tradition, reference URLs). A work groups together all editions of the same underlying translation.
• editions.tsv — one row per distinct edition (FK work_id). Carries the curated copyright status / category / statement / source URL / publisher / publication year — these are invariant across the sites that host the edition.
• instances.tsv — one row per per-site instance of an edition (FK edition_id → work_id). Captures the per-site declared copyright (which may disagree with the curated truth — useful for spotting publisher disputes).

This three-layer structure lets researchers define "uniqueness" for their own needs: deduplicate by work (translation family), edition (specific revision), or keep every per-site instance.

Usage

from datasets import load_dataset

# Load a single translation
ds = load_dataset(
    "mrapacz/targum-corpus",
    data_files="corpora/ebible.org/eng/eng-web.jsonl",
    split="train",
)
print(ds[0])

# Load all English translations from one site
ds = load_dataset(
    "mrapacz/targum-corpus",
    data_files="corpora/ebible.org/eng/*.jsonl",
    split="train",
)

Load metadata:

import pandas as pd

editions = pd.read_csv(
    "hf://datasets/mrapacz/targum-corpus/editions.tsv",
    sep="\t",
)
instances = pd.read_csv(
    "hf://datasets/mrapacz/targum-corpus/instances.tsv",
    sep="\t",
)
